LT1194
A scope photo of the amplifier output with no supply
bypassing is used to demonstrate this bypassing toler-
ance, RL = 1k.
In many applications, and those requiring good settling
time, it is important to use multiple bypass capacitors. A
0.1
F ceramic disc in parallel with a 4.7F tantalum is
recommended. Two oscilloscope photos with different
bypass conditions are used to illustrate the settling time
characteristics of the amplifier. Note that although the
output waveform looks acceptable at 1V/DIV, when ampli-
fied to 10mV/DIV the settling time to 10mV is 200ns. The
time drops to 162ns with multiple bypass capacitors, and
does not exhibit the characteristic power supply ringing.
Cable Terminations
The LT1194 video difference amplifier has been optimized
as a low cost cable driver. The
±50mA guaranteed output
current enables the LT1194 to easily deliver 7.5VP-P into
100
, while operating on ±5V supplies, or 2.6VP-P on a
single 5V supply.
When driving a cable it is important to terminate the cable
to avoid unwanted reflections. This can be done in one of
two ways: single termination or double termination. With
single termination, the cable must be terminated at the
receiving end (75
to ground) to absorb unwanted en-
ergy. The best performance can be obtained by double
termination (75
in series with the output of the amplifier,
and 75
to ground at the other end of the cable). This
termination is preferred because reflected energy is ab-
sorbed at each end of the cable. When using the double
termination technique it is important to note that the signal
is attenuated by a factor of 2, or 6dB. For a cable driver with
a gain of 5 (LT1194 gain of 10), the –3dB bandwidth is over
30MHz with no peaking.
A Voltage Controlled Current Source
The LT1194 can be used to make a fast, precise, voltage
controlled current source. The LT1194 high speed differ-
ential amplifier senses the current delivered to the load.
